TELEPHONE INSTRUMENT 0R THE LIKE.

Specification of Letters Patent.

Application ledAprl 26, 1918. Serial No. 230,963.

T 0 all 'whom 'it may concern.'

Be it known that I, OSCAR A Ross, a citizen of the United States of America, residing at 154 W. 57th St., New York city, in the county of New York and State of New York, have invented a new and useful Improvement in Telephone Instriunents or the like, of which the following is a specification. l

My invention belongs particularly to that class of telephone instrumentscomprising the receiving and transmitting units with cooperating circuit controlling devices commonly called av telephone stand and forms part of the apparatus known as the subscribers set.7

. My invention refers more particularly to that type of instrument which isportable within the limits of the connecting cord, or wire which attaches said instrument to the ringer unit.

Telephone instruments of well known construction and which `are now extensively employed, are usually constructed of two parts, one a receiver and the other the portable stand comprising the transmitter, a hook for holding the receiver andcoperating circuit controlling apparatus. In instruments of this type, a cord, or wire is supplied between the ringer unit and said portable stand, also a second cord is connected between said stand and the receiver. This second cord affords considerable nuisance as it becomes tangled and twisted, often breaking, thereby interrupting the circuit to the receiver and placing the instrument out of service. Further it is often in the way as the instrument is to be used and must be pre-arranged before telephonie communication can be carried on. One of the objects of my invention is to entirely eliminate said second cord, or wire by combining the receiver in said telephone stand, at the same time not destroying its feature of portability.

Further, when the two piece instrument is employed in places of business where it is necessary to use one hand for recording all, or part of the conversation carried on over such instrument, it is necessary to accommodate the body in a manner which permits thelips of the person talking to be within proper distance of the mouth-piece on said instrument. As it is often inconvenient and awkward to thus accommodate the body, conversation is carried on-with the lips a con* siderable distance from the transmitter, in this manner often requiring repetition of conversation causing annoyance and delay. Another object of my invention is to produce a telephonie instrument, which, while portable will compel the user of said instrment to maintain practically the proper distance between his, or her lips and the mouth-piece, or transmitter of said instrument.

Further, when a two piece instrument of many well known types is employed, it is very convenient to j oggle the hook, that is, to rapidly operate the lever controlling the cutting in and out of circuits to said instrument, in this manner calling attention of the station operator in an unnecessary manner.

VSuch practice is destructive to the hearing of switch-board operators and causes delay and annoyance. A further object of my invention therefore is to make such joggling of the hook difficult and inconvenient to do, thereby discouraging such practice.

All the above and other objects are attained in the instrument which, for purposes of lillustration is shown in the accompanying drawings, in which,

Figure l, is a transverse section through the preferred form of my instrument taken on line C-(l, of Fig. 4, and,

Fig. 2, is a plan view looking in the direction of line B-B, of Fig. l, and

Fig. 8, is a diagrammatic arrangement of circuits and appara-tus of a subscribers set, illustrating the adaptation of my improved instrument therewith.

None of the several units employed in Patented sept. 6,1921. I

makingup my improved instrument need be, of any special or unusual construction,

but for more ready understanding of my invention I have illustrated the transmitter and receiver as standard appliances employed by the American Bell Telephone Company.

The description of my improved form involving the heretofore named transmitter and receiver, is as follows:

Referring to Fig. 1, 1, is the receiver unit,

or topi piece of the instrument. 2,'is the vbase containing transmitter unit 74, of

' into and otherwise secured into receptacle 7 Said receptacleis rigidly secured to plateA 60, and sheet'metal housing 8, of base V2. Securedto tube 5, are collars 9 and 10, which a'ct as guides for movable tube 11. 12 and'lare felt-collars cemented to molded insulation 14 and receptacle and act to prevent dust and dirt from interfering with the proper movement of tube 11. Secured to tube 11, andV passing through the slotted holes 16, in tube 5, are screws 17, and 18.k

Screw 17, enters internally into screwAV 18, forming a double headed pin. Resting against shoulders of screws 17 and 18, are Vthe upper projections of yoke 19, said yoke being secured toand forming part of yoke 20, having kmounted thereon insulated sleeve 21, supported by pin 22, riveted into said yoke 20. `Operating tube11, is shown in its out of service position, the lower end there*Y of resting against stop 25, in receptacle 7.

. Aassume now that it is required to place the instrument in service for communication. The party using the instrument places his left hand around tube 11, and lifts the instrument from its place of rest. By this procedure, as the instrument is raised, the weight of the various parts causes tube 11, to move upward until its upper end impinges against stop 26. By this movement yokes 19 and 20, with insulating sleeve 21, are carried upward permitting contact springs 27 and 28, to contact with plate 29, thereby establishing the necessary: circuits to the receiver and transmitter of the instrument as illustrated in Fig. 8. Y rl"he functions performed by raising of tube 11, are analogous to those performed as the receiver is removed from-the hook of thertelephone as furnished by the American Bell Telephone Company.

If, for any reason it should be required to leave the instrument in telephonic'communication for any length of time, as for eX- ample, if the party using the telephone were compelled to leave` the room to call another party, Ythe pushV button 66, is depressed against the action' of spring 68, and tube 11, is permitted to lower intogroove 69, of push button 66. This position of tube 11, while permitting the Vinsulated, sleeve 21 to` approximate springs 27 and 28, does not cause said sleeve to force said springs away from plate 29 and therefore the instrument remains in service. Sleeve 67, is screwedonto v the innerextension of pushgbutton 66, and serves to limit the outwardmovement there-Y of.V When the instrument is again raised by tube 11, and as saidtube leaves the groove 69, in push button 66, said button will move outward under vpressure of spring 68A to the normal position. as shown, this action being automaticallyVV performed.

Contact'spring 27, is :riveted to terminal piece 61, and'spring'28, to piece 62. Said terminal piece isconnect-ed to terminal 36,'

of transmitter unit .74, by cable 63A The contact springsV v27V and ,'28 and Vterminal pieces 61 and 62Vtherefore arek clamped between insulation blocks 30 and 76, and -terminal plate 29, between blocks 76 and 77.l

Metal fplate 7 8 under Apre'ssure'of nuts 7 9?- 79, on studs as 80, serve to holdall said parts in place.V Studs as'80,.are secured to housing 8, preferably by welding.

Plate 60 has bent'up: lug 59, into a hole 'of which is threaded the anchor cord k58, of

vconductor cable 49, said anchor cordbeing wrapped around and tied to said lug 59.

This serves to prevent any. chaing of .the 'p cable and strains of the various branches running to their respective Vt'terminals as shown. Y Y. Y Y

Bottomcover plate V44, on its lower side is covered with feltsheetingll- Yretainedin place by band 48, saidband alSoenters into and serves to aline the entire cover unit 73, with base housing 8, being securedthereto by nuts 47 screwed onto studs 46-4, secured to said housing. Y.

In tube 5, are guide tubes as 50, in which pass the conductorsas 51, leading to termi-V nal posts 52-52, forming terminals for receiver unit coil-s. 42-42, mounted on soft iron pole pieces 39 Vand 4Q. Said pole pieces are embedded in molded 'insulation piece 1f and have angular extensions 71 and 72, which seat on the polar extensions of permanent magnet-37- Such seating is accomplished by the action of spring 65, one end of.V which forces magnet 37 upward, the other seating on pin 38, secured to tubeV 5.

Receiver unit 1, hask opening 82, covered Vby plate, orY cover 54, secured by screws 55 bedded in molded 'piece 14. Earpiece 43, screwed to molded piece'14, serves to accommodate the ear to receive,messages issuing rom'diaphragm 41, and also serves to hold said diaphragm inplace.

Transmitter unit 74, isfcomposed of daL phragm 3, the outer edge ci which is supported by bandfv Its center is secured to one terminus of the-microphone, the other end of which is secured to terminal post 36. Said terminal'post is mounted on but insulated from, by insulation 35, yoke34, secured to plates 70--70, by screws 75. Said plates 70, are secured to housing 8, preferably by welding.

able, or cord 49, forms the electrical connection between the instrument and the ringer set as illustrated by numeral 83, in Fig. 8. Said figure is a typical circuit inn volved in a subscribers set and which will be 'well understood by those versed in the art. 1, is the receiver unit, or top piece and 74 the transmitter as shown in Fig. 1. 27, 28 and 29, are likewise the contact members shown in the Figs. 1 and 4, and it will be suiiicient to relate that when said contact members are electrically connected with each other the receiver 1 and transmitter 74, aie placed in circuit to deliver and receive speech in a manner well known to those versed in the art. 84, is the usual condenser employed and 87 the induction coil. S5 and 86 are line wires communicating with the cooperating telephone exchange.

It will be evident to those skilled in the art that various modifications may be made without departing from the spirit of my invention. While I have herein shown and particularly described one embodiment or" my invention, I do not wish to be limited to the precise construction as illustrated, as changes may be made without departing from the spirit of my invention.
